Cotransfection of EloB/C does not affect VHL protein decrease. (A) HeLa cells were cotransfected with a panel of SOCS domain proteins and their respective BC-box mutant proteins. EloB/C were cotransfected as indicated (+ or −). Lysates were probed against VHL, EloB/C, and SAE1. Loading control: Actin. Decrease in SAE1 is specific to Gam1 WT protein expression and is the positive control. (B) Graph of VHL protein levels (from immunoblot in A) based on pixel-intensity values measured from plot profiles of individual lanes using ImageJ. (C–E) Immunoblots of transfected proteins with loading controls.
